GUYS: Have you ever been insecure with a beautiful girl?

I've noticed my relationships do not work out when I date someone for personality. I have been dumped by "less attractive" men. My relationships with more attractive men with the same amount of intelligence/success lasted. I've also seen some social science research showing partners choose others in the same physical range purely on looks.

I have had an ex tell me it was difficult to cope with the insecurity of other men looking at me constantly. This made me sad as I only had eyes for him and wished he would be more secure. At the end, his insecurity was hurtful to me and translated as a lack of faith in me. I was extremely heartbroken.
